' This invention relates to a box which is particularly adapted for use as a'powder container.

It is an object of the invention to produce abox which Issub'stanti'aIIy and attractively built and which will retain thepowder content without the possibility of. the latter dustingfrom the box. Q

' t is a further object of'the invention to produce a triangular box of this nature.

' l It is still a further object of the invention to provide a triangular box, thebody and cover of which are composed of paper or cardboard and thebottom of which consists of bakelite or a similar material, and which is so attached to the body of the box that it will seal the latter and will be retained inits attached condition.

- Th e box consists of a base 1, a selfcontained body portion 2 and a cover 3. In the l embodiment illustrated in the drawings, the

base, body'portion and cover are triangular in form, and while certain-phases of theinvention relate particularly to this form ina broader aspect the invention contem lates the construction of the boxin various orms. The body of the box includes a side wall 4, a bottom 5 and a top 6. The side wall is made of one continuous strip of material, preferably cardboard. This continuous strip of cardboard is bent into triangular planview of the bottom of the -which is preferably of folded over the upper e form and the end edges are broughttogether so thatflit is in this condition open at the and bottom. 7 This side wallis main tamed in its triangular form by the top 6', aper. This top is go of. the sidewall 4 and secured to the outer faces of the side wall by suitable adhesive. ZA'stri 7,. referubly of paper, covers the side wall an is secured thereto by an adhesive, so that. its u per ed e overlies the. turned over edges of the top 6 see Fig. 5). i

Thus, the side walls of the body :portion are maintained in their triangular form and the cover closes the body portion at the top.

The bottom 5 of the body ortion ,is tr1-' angular in form and of a size a apted to close I the bottom of the body portion of the box. This bottom 5 is secured to the lower. edge of the side wall 4.- by a strip 8, which is secured to the bottom by adhesive and to the outer. faces of the sidewall by adhesive beneath.

the strip 7. Thebottom of the body portion on the box is madeup of laminated material suitably secured together and in the lower lamination is an openingt). In the upper lamination is an opening 10 of a less diameter than the openin 9. The abutment 11 is formed by these 'lferent sized openinfis. These openin in the bottom portion of t e box are closerf by aremovable seal 12, which isformed as a result of the cutting'of the opcningl). When this seal is in lace it will snugly fit the opening 9 and retained therein byfriction and yet easily removable, and it will be revented from entering the interior of the body portion of the box by the abutment or flange 11.

1 Thus the body portion of the box will be a complete powder container unit which can be filled by the, removing of the sea-1'11 after 1 the various parts of thebody portion have been assembled, as described:=-

This body portion of the box thus assembled is attached to the base 1. This base 1 is made preferably of bakelite or-a similar material, and is provided with a depression or seat 13 for the reception of the body portion of the box. Thisdepression is formed by a flange 14 which surrounds the edge of the bottom. At the inner side of the flange are walls 15 which form a triangle substantially the same size as that formed by the outside of the wall of the body of the box and 5 are sufiiciently deep to embrace a considerable portion of the side walls of the body of the box. The relation between the size of these two triangles is such that the body of the box may be forced into'the depression 13 and will snugly fit therein, so that therewill be a frictional engagement between the walls 15 and the flange of the walls of the side of the body of the box to assist in maintaining the bod of the box and the bottom in assembled re ationship. This assembled relationship is further insured by the securing of the bottom of the body of the box to the bottom of the de ression 13 of the bottom by adhesive whic covers the contacting surface of the bottom of the body of the box.

The side walls of the cover of the box are made from a single strip 16 of material which is scored along lines 17 from the outside toward the inside of the strip, but only partly through the stri so that the inner surface of the strip is un roken and unscored. This strip is bent into triangular form so that the end edges abut each other and is formed preferabl of relatively stifi cardboard. These side walls of the cover are held in their triangular form by a strip 18 which covers the outer face of the walls of the cover, is relatively thinner than the material from which the side walls are formed and is secured thereto by an adhesive. The top of the cover is of a triangular form and is composed of a laminated material, the inner lamination 19 being equal to the inside measurements of the triangular wall of the cover and in as sembled condition abutting against the inside of the walls as at 20. The outer lamination 21 is greater in size than the inner lamination 19 to an extent equal to the thickness of the materials making up the walls of the cover. The result of this formation of the top of the cover from laminations of different sizes is that a flange 22 is provided on which the lower edges of the walls of the cover rest.

The to of the cover of the boxis secured to w the si e walls by a relatively lighter and more flexible material, such as paper 23. This is secured to the outer face of the top by an adhesive and overlaps the outer face of the side walls and the top. The side walls and these overlapping ed es are covered by a aper cover 24; which is olded over the free e ges of the side walls and secured to the outer faces of the side walls, as well as to the inner faces to the extent to which the paper overlaps them.

less than the width of the side walls 16 of the cover of the box, so that when the cover envelopes the body of the box the lower edge of the side walls of the cover will rest upon the abutment or ledge 25 of the bottom.

The size of the triangle .formd by' the body of the box is'substantially e ual to'the size of the triangle formed by t e inside wall of the cover of the box, so that the cover is held upon the body of the box by frictional en agement.

, at I claim is:

1. In a box of the class described, a triangular self-contained body portion, a triangular cover therefor, a triangular bottom of unyielding material for.the box having a de ression therein. for receiving the body portion, the side walls of said depression frictionally engaging the outer facesof the side walls of the body portion of the box. 2-. In a box of the class described, a triangular self-contained bodyortion formed of a single strip of .materia a triangular cover therefor, a triangular bottom for the box of relatively'greater thickness than that of the body of the box having a depression therein for receiving the body portion, the

sidewalls of said depression frictionally eng gging the outer faces of the side walls of the dy portion of the box, and an adhesive for securing the adjacent faces of the bottom and the body portion of the box together.

3. In a box of the class described, the com bination with a body portion, a bottom and a cover, said cover having side walls formed of a single strip of material, means for securing said material in a predetermined form, said cover having a top, the top being formed of laminations of diii'erent sizes, the edges of the inner diameter adapted to abut against the inner face of the side walls of the cover and the 1.1 per edges of the side walls of the cover a apted toabut against the outer lamination, and means common to said laminations for securing the latterv to'the side walls of said cover.

in testimony whereof, I havesigned my name to this specification this 5th day of November, 1929. a

The flange 14 of the bottom of the box forms an abutment or ledge 25 which is of a width equal to the width of the material of the side walls of the cover. The width of the side walls '2' and the body of the box is .ici
